Evaluation of Chest Radiographs and Laboratory Testing during Melanoma Staging Procedures.

Chest radiographs (CXRs) and laboratory testing have historically been performed as a part of low-risk melanoma (clinical stage 1/2) workup. This study evaluates the utility of routine CXRs and laboratory testing during the staging of clinical stage 1 and 2 melanoma patients. This study was approved by the Institutional Review Board at Wake Forest University. A database of sentinel lymph node biopsies performed for clinical stage 1 or 2 melanoma was used to identify early-stage melanoma patients. The medical records of patients with melanoma were reviewed and preoperative workup procedures were recorded. Four hundred sixty-three patients were reviewed. A total of 315 patients underwent a preoperative CXR, whereas 309 received some laboratory testing. After sentinel node biopsies, 168 patients had pathologic stage 1 disease, 103 stage 2, and 44 stage 3. None of the CXRs (0%) correctly identified metastatic melanoma. Suspicious locations on CXRs and laboratory testing did not lead to metastatic findings in any patient within a year. Metastatic melanoma was not found in any patient by screening with CXRs or laboratory testing during preoperative workup. We recommend not conducting CXRs or laboratory testing during workup for surgical melanoma patients because of charges and anxiety these tests can cause. CXRs, blood tests, and metabolic panels have historically been ordered for early melanoma patients, although debate remains on their efficacy. Surgical patient records were retrospectively reviewed for these tests and no benefit was found.
